We report an extremely rare case of an extraluminal interstitial pregnancy. A 36-year-old nulliparous woman visited our hospital during the fifth week of gestation. Although no intrauterine gestational sac (GS) was identified, transabdominal ultrasonography revealed a GS-like cyst was detected in the right uterine horn.

This study aimed to evaluate the frequency of CPP during the COVID-19 pandemic at a single center in the Osaka metropolitan area of Japan. We retrospectively analyzed the annual frequency of CPP occurrence before and after the first declaration of COVID-19 state of emergency in Japan at our hospital.

Materials And Methods: On 340 proband patients referred from across Japan, genomic variants were analyzed using a targeted multigene panel analysis combined with the multiplex ligation probe amplification (MLPA) analysis, mitochondrial m.3243A > G analysis and methylation-specific polymerase chain reaction of the imprinted 6q24 locus.
Objective: The practices pertaining to hereditary breast and ovarian cancer (HBOC) in Japan have been rapidly changing owing to the clinical development of poly(ADP-ribose) polymerase inhibitors, the increasing availability of companion diagnostics, and the broadened insurance coverage of HBOC management from April 2020. A questionnaire of gynecologic oncologists was conducted to understand the current status and to promote the widespread standardization of future HBOC management.
Methods: A Google Form questionnaire was administered to the members of the Japan Society of Gynecologic Oncology.
MicroRNA-152 (miR-152) expression has been reported to be associated with poor prognosis in patients with endometrial serous carcinoma (ESC). However, the function of miR-152 in ESCs is not fully understood. The present study aimed to investigate the involvement of miR-152 in ESC progression.

Objectives: Constitutional delay of growth (CDG) is usually associated with a delay in pubertal onset (CDGP) and a catch-up growth after puberty. Some individuals, however, have earlier-than-expected pubertal onset resulting in a shorter adult height. We investigated the current incidence of such individuals and that of 30 years ago.

In this retrospective analysis, we evaluated the usage patterns of bevacizumab administered for platinum-resistant recurrent ovarian cancer.
Methods: We obtained clinical data from 155 Japanese medical facilities between November 2013 and December 2018 via a survey.
Identification of the population frequencies of definitely pathogenic germline variants in two major hereditary breast and ovarian cancer syndrome (HBOC) genes, BRCA1/2, is essential to estimate the number of HBOC patients. In addition, the identification of moderately penetrant HBOC gene variants that contribute to increasing the risk of breast and ovarian cancers in a population is critical to establish personalized health care. A prospective cohort subjected to genome analysis can provide both sets of information.

Paclitaxel, a key drug for endometrial cancer treatment, inhibits microtubule depolymerization and induces apoptosis in cancer cells. Endometrial serous carcinoma (ESC) accounts for < 10% of all endometrial carcinomas, but its aggressive nature makes it responsible for close to 40% of cancer deaths.

This ad hoc analysis of the CHARLOTTE epidemiological study in Japan assessed the distribution of gBRCA1/2 mutations in patients with newly diagnosed ovarian cancer, and investigated an association between gBRCA1/2 mutation locations and ovarian cancer risk. Differences in patient background and clinical characteristics in subgroups stratified by gBRCA1/2 mutation locations were also evaluated.

Methods: Among patients enrolled in a randomized phase III trial (JGOG2043) investigating the efficacy of adjuvant chemotherapy for endometrial cancer at a high risk of progression, the recurrent patients were studied. Clinical information were collected, and correlation between relapse-related factors and clinicopathological factors were analyzed.
Introduction: gene mutations are associated with hereditary ovarian cancer. plays a key role in genome integrity, and mutations result in an increased risk for ovarian cancer. Although various guidelines recommend testing in patients with ovarian cancer, data on germline (g) mutation frequency in ovarian cancer in Japan are scarce.

Total hysterectomy is divided into two types: the extrafascial and intrafascial approaches. Intrafascial hysterectomy, represented by the Aldridge's method, is a useful and safe procedure for treatment when the patient has no cervical malignancy, including cervical intraepithelial neoplasia.

Objective: To evaluate the clinical benefit of taxane plus platinum compared with standard doxorubicin plus cisplatin as postoperative adjuvant chemotherapy in endometrial cancer.
Design, Setting, And Participants: In this multicenter, open-label, phase 3 randomized clinical trial, patients with endometrial cancer at high-risk stage I or II or stage III or IV that did not extend beyond the abdominal cavity and had 2 cm or greater residual tumor were included from 118 institutions in Japan from November 24, 2006, to January 7, 2011.
Aim: Leiomyosarcoma is the most common type of uterine sarcoma. In some leiomyosarcoma cases, preoperative diagnosis might be difficult, and they might be treated as benign lesions. We evaluated diagnostic values of preoperative serum lactate dehydrogenase (LDH), D-dimer and C-reactive protein for differentiating leiomyosarcoma.

Methods: A multicenter clinical survey was conducted at three Japanese institutions. Clinical data in patients with PFTC between 1998 and 2016 were collected.
Objective: To examine the surgical-pathological predictors of para-aortic lymph node (PAN) metastasis at radical hysterectomy, and for PAN recurrence among women who did not undergo PAN dissection at radical hysterectomy.
Methods: This is a retrospective analysis of a nation-wide cohort study of surgically-treated stage IB-IIB cervical cancer (n=5,620). Multivariate models were used to identify independent surgical-pathological predictors for PAN metastasis/recurrence.
Primary osteosarcoma of the uterine cervix is extremely rare. Only 20 cases have been reported, 19 of which originated in the uterine corpus. We report a case of primary uterine cervical osteosarcoma with pulmonary metastasis in a 30-year-old nulligravida woman.

Methods: We conducted a retrospective cohort study between 2011 and 2014 in member institutions of the Tohoku Translational Research Center Development Network.
Results: A total of 53 patients with ULMS were registered in 31 institutions for the present survey.
Leptomeningeal metastasis (LM) is rarely observed in gynecologic cancers. As gadolinium-enhanced magnetic resonance imaging (Gd-MRI) is highly effective for diagnosing LM, the aim of this study is to describe the clinical behaviors and outcomes of LM patients who were diagnosed by Gd-MRI. After securing institutional review board approvals, we retrospectively reviewed patient records.
